Abstract:

The invention relates to novel composites for capture, e.g., absorption, of condensable gases and vapors from atmospheric sources, and gas or vapor streams, and the recovery of the condensed gases and vapors from the composites, as well as passive methods absent of external sources of energy for conducting the capturing and recovery processes. The composites include a hydrophilic matrix; hydrophilic solids embedded or immersed in the matrix, in close proximity to each other; and porogenic material embedded in the matrix, having a size larger than the hydrophilic solids; wherein selective removal of the porogenic material from the matrix forms a hierarchically porous matrix.
